Title		GRAIN LENGTH AND AWN 1 negatively regulates grain size in rice.
Abstract: grain size is an important factor determining yield in rice. Here, we identified a recessive mutant gene, GRAIN LENGTH AND AWN 1 (gla1), which caused a significant increase in grain length and weight, and was associated with long awns. The gla1 mutation was mapped to a single-nucleotide polymorphism in a gene encoding a cytoplasmically-localized mitogen-activated protein kinase (MAPK) phosphatase. Overexpression of gla1 caused a decrease in grain length, and the gla1 protein interacted with OsMAPK6. These results suggest that gla1 may serve as a negative regulator of the OsMAPKK4-OsMAPK6 cascade, controlling grain size via the dephosphorylation of OsMAPK6.
